Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any site, sometimes even by 100%, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall server load and to accelerate the browsing speed for the site visitors. Every time a visitor opens a page on a particular website, the web browser request is processed by the web server and the requested content is sent as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor browses and in case any of them is accessed once again, it’s fetched by Varnish and not by the server directly. The boost in the performance is due to the fact that the accelerator processes the web requests significantly quicker than any web server, which results in much faster browsing speeds for the users. If any content is edited in the meantime, the cached pages will also be ‘refreshed’ the next time somebody attempts to access them.
Varnish in Shared Hosting
Varnish comes as an optional upgrade with all our shared hosting. You can add it to your account through the Hepsia hosting Control Panel, which is available with all shared web hosting plans and you will get a pretty user-friendly GUI, which will give you full control over the content caching platform. Using one-click fast-access controls, you can reboot or delete any of the instances, in other words – Varnish will no longer be enabled for a certain Internet site. You can also see an in-depth log or clear the cache for any of the sites. When you add Varnish to your web hosting plan, you’ll be able to choose the total amount of system memory that will be available to you for caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can set a dedicated IP address for the sites that will use Varnish. This will permit you to take full advantage of your sites and to have lots of gratified site users.
